mraovsmsm'm Massages snooze,

Be it kriown that I; Joan B'nnar, of the city and county of Sanllanoisico, State of California, have invented certaiu new and usefulImprovements in Street-railroad Oars;". andI do hereby declare that thefollowing is a full, clear, and exact descriptlop of the some,reference-being had to the aeoompanymg drawings and to the lettersmarked thereon.

My mvention .relates principally to improvements in the-construction ofthe trncks'oi' strechrailway cars, whereby thewell-known' difficultiesattendant upon turnipg curves is obviated, and consists in pivotingeacli truck independently to the bottom or, platlbrm of the car, so thatthe trucks oalr be' moved laterally, and conform to the curvature'oi'Ithe road by simply operating thehrake-s piridle. f

The truck, frames [extend to the cadet hoi'h' plati'orms of the .car,and are provided with a rack, theteetlr of which are engaged by,apinion' upon the make-spindle, which is forced hack againstthe platformhy a spring when not in use, and admits of the brake-spindle beingemployed in the ordinary way again. i

, In the di ai$'i ngs'- l s Figure l'represents a plan of my inrcntion.

Figure 2, a side elevation.

Like letters refer to like parts;

To enable others 'skill'edint-he art or science to which it mos.nearlyappertains to make and use my invention, I \vrll procecdtofnllytdes crihe its construction and operation.

A represents the truck-frame, in which the axle D h s its hearings. .lheframeris pivoted to the'thot'tom of the car by the pin E, and extends tothe end of g lleplatfiirm, and is nearly flush with thesaid; platorm. 1a A curved raok,1 ,is,prqvided for theend of the frame, thete'eiliz ofwliich, are engaged by the pinion G on the bra spindle G, which causesthetrnokflame, and with it the wheels,'to moveright or left, as desired.I Theiendof the truck-flame rests on a; block, H, which isprovidedwith aforked arm, H, which guides the hrake-spindlcbeneath the pinion. Thepinion is loose.onthespiude, and drops when l the forkcdarm is presseddown,'-a nd iscarried ba'ck again to its p0: sitionjivhen the pressureis removed fromthe arm.

The arm moves 'iuthe block on pinsl I, by pressure of the foot upon abolt, J attached to the arm ,H', which passes up through the platform ofthe car, and alflat. swing-K, holds thearmvto its placeagain'st thelower face of theiblock. I j

111 operating my devicqsufiicient play is'given to the pinion and hrakespindle-to allow the pin on '30 fall by pressure upon the bolt, in ordertoengage in the teeth of the rack at theend of the truck frame, when, byturning the" brake'spindle to the right or left, the frameis moved, andwith it the wheels, at t-he desired angle, according to the direction ofthe curve of the track, and, when the pressure is removed from'the bolt,the arm flies hack to, its position against thebloolglhy means of 'thespring, :and carries with it the pinion, when the brake-spindle may heemployed as usual to stop the car, for it is not intended that theposition of the pinion on the spindle -sl |al,l intcrfere with itspelfect working inthe capacityof a brakespindle. t a

If'the block in which 'n|eend of thejtrnck-l'rame moves and-pirhichsupports it should not he found sufficient, slots may bemade in theframe, andmove on other supports or bolts', v'ith heads, attached to thelmttQm of thevcar. I I

My improvement will 'also'he found a great auxiliary in getting the carhawk upon the hack, after it has been thrown off. k I t I am awarethatvarions attempts .har'e hcen made to obviate the.diliieultiesattendant upon turning curves with cars on strect-railwaysbydii'idlngthc' axles and the use of box-couplings, or bythe employment ofan independent wheel to overcome the sliding process or friction oi' thefixed wheels. and of other devices too numerous to mention in tl1isconnection; but none, I believe, have been found so efficient for thepurpose as my own invention.

Hayingz' thus described my invention,

7 What I claim, and desire to secure by Letters Iatent,is--.- ,4 1. Therack F at the end of the frame, and pinion G attached to thebrake-spindle, so L that, by operating the said brake-spindle, theposition of the truckflameand wheels canbe changed from left to'right orright to left',.suhstant ially as and for the purpose specifie l t 2.The forked arm H, whiohguides'the lower end ofthe brake-spindle movingon the=pins I I in the block H, substantially as" described.

4. The spring K, for -holding-the arm against the block H, and thefoot-bolt J, passing out through the platform for; pressing down thearm,'suhstantially as described- Intestimony whereof I have hereunto setmy-hand and-seal. a p v JOHN BERRY. [as] Withesseszx 0. W.,M. SMITH,
